A review of the weekend's action in the Dutch Eredivisie.

Dries Mertens and Jurgen Locadia fired hat-tricks as PSV Eindhoven rampaged to a 6-0 win over VVV-Venlo in the Eredivisie.

Four of the goals - including all of substitute Locadia's efforts - came in the final quarter of an hour to give the scoreline a more lop-sided look than had appeared likely.

Mark van Bommel's deft lob rebounded off the frame of the goal before Mertens emphatically slammed home Ola Toivonen's cross in the 23rd minute and he then curled home a second with the outside of his right foot in the 35th.

VVV's Uche Nwofor, booked for a show of petulance after he appeared to be illegally prevented from shooting in the first half, received a second yellow card in the 65th minute and that, coupled with the introduction of Locadia three minutes later, allowed the visitors to swell their goal tally.

Toivonen set up the Holland Under-19 international to mark his Eredivisie debut with a goal and Belgium striker Mertens completed his treble with a solo effort in the 79th minute.

Locadia converted a cross from fellow substitute Wilfred Bouma three minutes later and the 18-year-old rounded off the scoring five minutes from time.

The win leaves PSV three points behind leaders FC Twente, whose 100 per cent record was ended by defeat to Ajax on Saturday.

FC Groningen's Michael de Leeuw also netted a hat-trick, including an injury-time winner, to earn a 3-2 success against 10-man Roda JC.

De Leeuw tapped in Virgil van Dijk's knockdown in the 17th minute and Roda had Tamas Kadar sent-off straight from the restart for a foul denying a goalscoring opportunity.

But they equalised on the stroke of half-time through Mark Jan Fledderus - who himself had been lucky to escape a red card in the early stages.

De Leeuw scored again on 53 minutes but Amin Affane's 20-yard strike 12 minutes from time looked to have earned Ruud Brood's visiting side a point.

Groningen had other ideas, though, and it was De Leeuw again who broke Roda's hearts in the final seconds.

AZ Alkmaar twice let the lead slip before earning a 3-3 draw against RKC Waalwijk with a late equaliser.

Adam Maher brilliantly set up AZ's opener for Viktor Elm, the Sweden midfielder arriving to head home his fourth goal in as many days following a midweek hat-trick against SC Veendam.

Teddy Chevalier brilliantly beat his marker Etienne Reijnen to equalise in the 16th minute but Eredivisie top scorer Jozy Altidore restored AZ's lead in stunning fashion, slaloming through four defenders before firing into the bottom corner.

The lead lasted only three minutes on this occasion, Frank van Mosselveld equalising after Rodney Sneijder's free-kick was blocked.

AZ's recurring weakness from set-pieces reared its head early in the second half as Henrico Drost was left unmarked to head home a corner.

The hosts had to wait until the 86th minute for their equaliser as Maher, who had earlier been denied by the woodwork, finished after Altidore flicked on substitute Mikhail Rosheuvel's cross.

PEC Zwolle recorded their first win of the season, 1-0 away to Willem II.

Wiljan Plume struck a post in a goalless first half but Zwolle made the breakthrough straight after the interval when Bart van Hintum curled home a free-kick from the edge of the penalty area.

Giovanni Gravenbeek came close to a second against his former club, but home keeper David Meul made an excellent one-handed save.

On Saturday, Twente saw their perfect start to the new season come to a crashing halt as they slumped to a 1-0 defeat at Ajax.

Twente had won all six of their league matches prior to Saturday but saw their lead at the top of the standings trimmed as Christian Eriksen struck the only goal for the Amsterdammers in the 68th minute.

Ajax's win saw them close to within three points of their beaten opponents, while second-placed Vitesse Arnhem also profited as they moved to within a point of the summit with a 2-1 win at FC Utrecht.

The visitors took the lead through Marco van Ginkel in the 55th minute and Wilfried Bony made it 2-0 just five minutes later.

Substitute Jacob Mulenga pulled one back for Utrecht in the 71st minute but unbeaten Vitesse held on for their fifth win in seven league outings this season.

Feyenoord are fourth, two points shy of Ajax, after a 5-1 thumping of NEC Nijmegen.

Lex Immers struck a hat-trick for the victors, tucking home a 47th-minute penalty before adding further strikes in the 63rd and 85th minutes.

Graziano Pelle (16, 44) added a brace for Feyenoord, while NEC replied through Soren Rieks four minutes into the second half.

ADO Den Haag remained in seventh place after a battling 3-3 draw at Heracles Almelo.

Lerin Duarte's own goal handed ADO a 12th-minute lead that kicked off a crazy spell of three penalties and five goals in just 20 minutes.

Willy Overtoom levelled from the spot for the hosts eight minutes later, but four minutes after that ADO had a spot-kick of their own that Danny Holla tucked away.

The referee pointed to the spot again in the 29th minute to allow Overtoom to pull Heracles level for the second time, while the hosts went in front in the 32nd minute when Ninos Gouriye fired home.

The excitement died down after that breathless passage of play, but there was still a twist to come as Holla popped up with his second in the 73rd minute to ensure it finished all even.

In the day's final game, Heerenveen picked up their first win of the season with a 2-0 victory over NAC Breda, Alfred Finnbogason (nine) and Daniel De Ridder (40) with the goals.
